Application Tools

When grinding hardened steels and tool sharpening hss conventional abrasives, in the processing zone there are significant cutting forces and high temperatures reaching the melting point processed material. This leads to poor quality of the work surface, reducing the tool life of high-speed steels. In addition, conventional abrasive wheels have a low resistance, which causes them frequent correction and readjustment. High flow rate of abrasive wheels, low surface quality, low productivity, dust the work area – the main drawbacks of conventional grinding wheels More progressive is the processing of synthetic superhard materials based on cubic boron nitride (Elbor, kubonit, hexane-A, CBN). Crystals cbn (cubic boron nitride) have increased fragile and as a result of cleaving the crystals during grinding, cutting edge is constantly being updated and thus ensured self-sharpening tool.

cbn wheels have high cutting capacity, which in some times the cutting ability of communities from conventional abrasives. High cutting power circles of the cns remains to complete wear. As well as cbn and diamond differs from conventional abrasives higher thermal conductivity and low heat capacity, which provides intensive heat removal from the grinding zone. This allows the grinding process more intensively and at the same time to receive the processed surface of the product without burns, phase and structural changes in the surface layer. No less important advantage of css is its chemical inertness in contact with different kinds of steel. Unlike diamond and silicon carbide, cbn inert to iron at temperatures up to 1200 C. This reduces the cutting force, temperature and prevents the "brining" grinding wheels. Low temperatures in the cutting circles cbn exclude the possibility formation of tensile stresses in the surface layer and, conversely, promote the formation of compressive stresses that have a positive effect on the wear resistance of workpieces and tools. see details

Earth Power

Also avoid emissions of pollutants that are generated in the use of fossil fuels, reducing the consumption of fossil fuel reserves, other and generating very little amount of fuel much more energy. Drawbacks there is a high risk of contamination in case of accident or sabotage. Produce radioactive waste that are difficult to store and are active for a long time. It has a high and prolonged costs of facilities and maintenance of nuclear power plants. It can be used for warlike purposes. Solar energy is energy obtained by means of capturing light and heat emitted by the Sun. This can be obtained, thermal energy and solar energy photovoltaic solar radiation that reaches the earth can be leveraged through the heat produced through the absorption of the radiation, this is known as solar thermal energy. ES one so-called renewable energy, particularly in the non-polluting group, known as clean energy or green power.

The power of radiation varies with the time of day, weather conditions that dampen it and latitude. It can be assumed that in good conditions of irradiation value is approximately 1000 W/m at the Earth’s surface. This power he known as irradiation. The direct radiation is directly coming solar focus, without reflections or refractions intermediate can be reflected and concentrate for use, according to studies, solar photovoltaics could supply electricity to two-thirds of the world’s population. This non-polluting and natural, energy is an inexhaustible resource, which is within the reach of all, using a team of great efficiency in harvesting this energy, so it would be a medium power not to contaminate you free saving money and avoiding altogether and large amounts of co2.

Astuce De L

Presque tout le monde aime écouter de la musique. Pour les amateurs de vraie musique, il y a une nouvelle astuce, qui est aussi souvent dénommée la musique dite monstre maintenant sur Internet. Il s’agit d’un taux forfaitaire pour la musique, avec lequel vous pouvez enregistrer chaque mois autant de musique que vous voulez. Donc limitée aux tarifs de téléphone non plus seulement de taux forfaitaires, télévision par câble ou l’Internet, mais sont maintenant présents dans le monde de la musique. Il fonctionne avec les dimensions suivantes : un portail spécial (c’est appelé principalement de musique monstre) se connecte à. Cela permet d’écouter autant de musique qu’il aimerait l’utilisateur moyennant un tarif mensuel de 10 euros environ. En écoutant cette musique à l’aide d’un lecteur spécial qui représente une Web radio en principe, sauf qu’elle comprend un enregistrement automatique.

Cependant, ça ne sonne pas n’importe quel titre, mais peut souhaiter avec des listes de souhaits même joués de la musique et mis en place. Où est la musique que vous le souhaitez, puis automatiquement compte rendu peut être Télécharger MP3 je reçois les chansons sur son ordinateur et elle a désormais pour toujours et à jamais. Maintenant, vous pouvez le graver sur CD, écoutez à la maison ou en déplacement, ou transfert sur votre propre lecteur MP3. Qui n’est pas sûr de savoir si une musique forfaitaire est quelque chose pour lui qui devrait consulter d’abord un fournisseur qui permet à ses utilisateurs de libérer des périodes d’essai. Donc vous pouvez convaincre vous-même des avantages d’une musique Flatrate elle-même peut être et décider ensuite si vous voulez ou de ne pas prendre un abonnement payant pour un tel chantier. C’est sûr, mais, musique de monstre, maintenant considérée comme absolue petit secret parmi les amateurs de musique.

Constant Noise

One of most annoying disorders, or by those who most complain those who suffer from tinnitus (symptom that is characterized by a constant noise in the ear), it is the fact of being able to not fall asleep due to these unbearable humming. In fact many people support and learn to live with tinnitus so far that they begin to interfere with the hours of rest. Usually at night when the ambient sounds are attenuating, shaped inversely proportional, the tinnitus sounds begin increase their level of perception. In many cases the tiredness or relaxation expire easily this acoustic phenomenon and does not cause major problems. It is like when someone moves near a highway or an airport; at first the noise seems unbearable, but as they spend the nights, the brain gets used to these noises and do not pay attention to them. But there are more serious cases of a constant noise in the ear, which often depend on the particular characteristics of each person, where the sound of tinnitus becomes unbearable and It remains at all times as a focus of attention of who suffers it. There are ways, that although they are not very scientific, can help to relax this type of tinnitus patients.

The most successful methods taken from the experience of tinnitus patients are those who plug or masking tinnitus (a name also given to tinnitus). These methods are based on redirect the attention of the patient towards another sound. For example; You can leave the TV or the radio lit throughout the night, or in instances more serious where the perception of tinnitus is greater than the background sound, you can tune the radio no off-season doing white noise to cover or conceals the own of tinnitus buzzing. There is a method of little known but very effective is guaranteed to make that tinnitus will disappear forever.
